Development of a retrofit coal combustor for industrial applications
During this quarter the tandem design configuration unit was tested on a low ash pulverized coal. The test results confirmed operation with strong peak-to-peak pressures and high carbon burn-out efficiencies. These configuration units were dismantled after testing with micronized coal (see third quarterly) and pulverized coal during this period. The refractory material in one of the chambers failed, probably due to improper curing during installation. Design modifications based on performance were incorporated into both the combustors and the facility. The tandem unit was modified and evaluation testing initiated. Performance on 100 percent pulverized coal was similar to performance on micronized coal indicating that the unit has a high degree of tolerance and flexibility for a spectrum of fuel types.
